Investigatory powers – Regulation of investigatory powers. The obtaining of the complainants' communications data by authorisations granted under the Regulation of Investigatory Powers Act 2000 s 22(3) had been unlawful. Accordingly, the Investigatory Powers Tribunal quashed the authorisations, and ordered the communications data obtained under them to be deleted, with an exception and the respondent Metropolitan Police Commissioner to pay the first complainant compensation of £5,000, as there was a sufficient causal connection between the infringement of her rights and the stress condition diagnosed.
